Just seen this Onzz.When going back to older firmware it is always a good idea to reformat the application area...Once you have 5020 loaded on your computer rename it patch.bin
Put it on a zip drive and install it into your AZ receiver powered down...Flip the switch and your AZ will reboot checking etc!..A blue screen will come up and you will have several options and one of them will be reformat the application area...Reformat the application area...I usually do that 3 times when going to older firmware.After it is done scroll down on that same blue screen to update by usb.
That will do it for you Onzz..But there is no NA sat list with any firmware older than 5308!..You will have to create your own using AZEdit and MAZ 3.2. Or what you can do is save the SAT,CH list from 5308 or 5309 using the ACC program then after you are done installing 5020 just crank up the ACC program and send the SAT,CH list that you have saved back to your AZ.
Good luck.
Sorry about the PM.....Thanks for the reply ...This is good info to know for the future... Much appreciated!
